Abstract: 1,233,267. Arc spot welding systems. MESSER GRIESHEIM G.m.b.H. 14 June, 1968 [15 June, 1967], No. 28365/68. Heading H2H. Arc welding apparatus comprises means for terminating the welding process after a predetermined time interval, the means forming a short circuit in parallel with the arc which is completed at the desired moment. The arc welding process may be used in spot welding apparatus having an electrode 15 and workpiece 16 which are supplied from an A.C. source 13 over contacts 11 and a transformer/rectifier unit 10. The contacts 11 are closed by a relay 12 which is energized by closure of a push button 14, the contacts 11 also forming a self-holding contact for the relay. Closure of a contact 19 by a current relay 18 energizes a time delay relay 20 which, after a time required by the welding process, closes a contact 21 to apply a signal to the gate of a thyristor 27 which becomes conductive to short circuit the electrode 15 and workpiece 16 thereby extinguishing the arc. Conduction of the thyristor 27 also energizes a current relay 30 which causes contacts 29 to open thus de-energizing relay 12 to open contacts 11 to reset the apparatus for the following operation.

Ketones are purified by countercurrently contacting an inert gas with a solution of the impure ketone and separating the so-purified ketone from the solvent. The solvent must be miscible with the ketone but not form an azeotrope therewith and should not be able to dissolve paraffins or olefins. Suitable solvents include water, ethylene glycol, diethylene glycol, dimethylsulphoxide, N-methylpyrrolidine and tetramethylene sulphone and is preferably used in an amount of from 5 to 80% by weight with respect to weight of ketone + solvent. Examples describe the purification of acetone obtained by the catalytic dehydrogenation of 2-propanol.

Abstract: 1,238,826. Controlling contrast. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. April 17, 1968 [April 19, 1967], No. 57643/70 Divided out of 1,237, 705. Heading G2C. In an arrangement for modulating the contrast of a transparency image, the transparency or film 41 is supported on a semitransparent reflector 46 opposite a phosphor screen 45, and is exposed to radiation from a source 42. As shown, the source 42 is an ultraviolet lamp whose light is reflected by a semitransparent reflector 43 through lens 44 on to the film 41 which itself rests on a semitransparent plate 46. Thus the light reflected back from film 41 has an intensity distribution corresponding to the relative light transmissivity of the image on film 41. This reflected light is projected through reflector 43 on to the phosphor screen 45, which luminesces with the same intensity distribution. Light from screen 45 is now projected through reflector 43 and lens 44 back on to film 41. Thus the contrast of the film image is enhanced, and may be observed from the other side of plate 46, or a sensitive sheet may be placed below the plate and a print made. If the screen 45, instead of being of a material which luminesces in response to incident light, is of an infrared quenching phosphor, and the light source 42 is an infrared lamp, the contrast of the image will be reduced instead of enhanced.

Abstract: 1,264,445. Adjustable headlamps. ROBERT BOSCH G.m.b.H. 23 Nov., 1970 [22 Nov., 1969], No. 55539/70. Heading F4R. Apparatus for adjusting the inclination of the beam of a motor vehicle headlamp comprises a switch for transmitting electrical impulses to an electromagnet to cause displacement of an adjusting device extending between the fixed and moving parts of the lamp. The switch, Fig. 1, fitted to the vehicle dashboard comprises a ratchet-wheel 2 which is turned by a handle operated by the driver to displace a pin 3 against a spring 4 to make contacts 6, 7 which close the circuit to the electromagnet. The adjusting device, Fig. 3, comprises a ratchetwheel 12 operated by a dog activated by the electromagnet in response to the switch, this ratchet-wheel having an eccentrically located pin 13 which on rotation of the wheel drives a lever 16. As the body of the adjusting device is attached to the lamp reflector 18 and the lever 16 is attached via pin 20 to the body of the vehicle, this movement causes tilting of the reflector with consequent adjustment of the beam inclination. Initial adjustment is made using bolt 21 between lever 16 and the vehicle body. To provide a quick return mechanism, restoring the reflector rapidly to its original undeflected position, trip cams 22 are provided around half of the ratchet-wheel 12, these cams operating switch contacts on rotation of the wheel to cause automatic stepping of the electromagnet and ratchet-wheel over the arc covered by the trip cams, this arc corresponding to positions of the reflector between fully deflected and original positions.

Phthalazinone is also preferably present. The mercuric ion may be supplied in the form of a halide which will react with the organic silver salt to form the photosensitive silver halide in situ. Sensitizing dyes may be present. On exposure to a light image followed by heat development using the minimum heat to produce maximum useful density in the unexposed areas, a positive image is obtained.

The capacitor 4 charges above the voltage of the battery, and the discharge circuit includes an additional inductor 10 which may be shortcircuited by a switch 7 if coil 11 is itself sufficiently inductive. A reservoir capacitor 3 maintains the supply voltage during charging. The thyristor 8 may be triggered via a second thyristor to which the generator 9, whose pulse rate is adjustable, is connected. The coil 11 may be introduced into an underground passage for location by a magnetic field detector coil at the surface; after determining the point on the surface immediately above the coil, the distance from this point at which the field reduces to zero in the horizontal plane may be used to determine the depth. Alternatively, the coil may be placed on the surface and an underground pipeline located by detecting the disturbance to the field of the coil. Constructional details of the transmitting and detecting coils are given. Fig. 3 shows an oscillator (9) for triggering the thyristor. It is started by closing switch 26 in the base/emitter circuit of transistor 21, whose conduction rapidly increases until capacitor 30 is charged, whereupon conduction ceases until 30 is sufficiently discharged through resistor 35, when the cycle repeats.

Abstract: 1318226 Tufting SHORELL Ltd 9 Dec 1971 [31 Dec 1970] 62092/70 Headings DIG and D1K In a tufting machine a stop 20 cooperates with a needle 1 to locate the tuft in the backing fabric 9. The stop 20 may be a stationary plate but as shown separate stops 20 corresponding to the needles 1 are reciprocated by an eccentric 17 on the shaft 7 which reciprocates the needle bar 2 through a second eccentric 6. Separate pattern controlled electrically operated tuft measuring and cutting devices 32, 34 are associated with the branch pipes 29..31 of a compressed air feed-pipe 28 leading to the needle entry orifice 27. When a needle is retracted the appropriate device 32, 34, is operated to feed the desired coloured tuft into the needle which then pierces the fabric 9. A ram 14 descends with the needle to locate the upper end of the tuft and the stop rises to locate the lower end of the tuft, the ram 14 and stop 19 remaining stationary until  the needle has retracted above the fabric and the tuft is gripped by the fabric. The backing ends of the tufts are sprayed with adhesive 38 which is dried by a heater 51. The fabric 9 is advanced intermittently by a ratchet driven take-up roll 13, the fabric being stationary while the needles pierce it.. The needle is reciprocated by an angularly adjustable eccentric 42, Fig. 2, which is connected to the needle operating lever 47 by a strap 44 adjustable in a slot 46, whereby the stroke and timing of the needle may be varied. A modified stop, Fig. 5, comprises a horseshoe shaped member 50, on a block 19, which permits the tuft to be slid sideways out of the stop when the fabric moves forward.
